FTM and changes in my 20 month old

sherry

So I’d say the past couple months my little one has at a complete change in her attitude. She use to not cry or throw fits but now that’s all she does. She will scream and cry about anything or everything. She also recently start yelling “No” about anything and everything. I’ve tried everything and I feel defeated… I feel bad because I get overwhelmed and overstimulated so I need advice. Is this just her entering the terrible two’s? 🥲
